At one point in time, Rolando McClain was foreseen as the kind of building block defender that could be the heart of an NFL defense. The Oakland Raiders invested the No. 8 pick in the 2010 draft on him, and in spite of racking up 244 tackles in three seasons, he wasn't the difference-maker they thought he'd be. That lack of on-field production -- coupled with some malfeasance off the field -- led the Raiders to first try to trade him, then waive him.
